I remeasured the OD shim tonight and I got a nasty surprise. I must have messed up my original measurement somehow. I am glad that you stressed it and that I double checked it.
The correct measurement average is 1.828. The Sonnax shim plus one spacer brings me to .185. The FSM says range is 1.8250 - 1.8399. Shim thickness .183 - .185. Would you leave it at .185 or add another .010 shim?
I turn off the OD unless I'm on the highway, I was told that it would make my trans last longer.
